Kirkland Signature 2200 High Performance Furnace Filters deliver MERV 13 filtration efficiency in a 20" x 25" x 1" size, sold in a convenient 4-pack. Designed for residential and commercial HVAC systems, these filters use electrostatically charged fibers to attract and capture both large and microscopic airborne particles, helping maintain healthier indoor air quality throughout your home.

Each filter captures smoke, pet dander, lint, dust mite debris, pollen, smog, airborne bacteria, mold spores, household dust, and particles that carry viruses and odors. Kirkland Signature's 2200 MPR rating means these filters capture and hold 30% more dust and particulates than other elite allergen filters, making them an excellent choice for households with pets, allergy sufferers, or high dust environments.

Featuring Dual Airflow Technology, these filters can be inserted in either direction for easy installation. Each filter provides up to 90 days of airflow performance, and Costco recommends replacement every 3 months — more frequently in homes with pets or elevated dust levels. Rated 4.6 out of 5 stars by over 2,400 Costco members.
